(Black/Red) 8 LD Aggro V2

this is my beta version of black red aggro post shadowmoor. i think the inclusion of eight land destruction spells will give this archetype an advantage over other aggro decks by land colour screwing them, or stalling mid-range and control decks long enough to gain a decisive advantage. however, this build is untested and the sideboard is based on the pre-shadowmoor metagame, so any constructive comments on card choice, sideboard plans or general match-up information would be appreciated. thank you. after some minor testing i have come to two realizations. one: scarscale ritual is near useless at sorcery speed, and two: i was nearly always colour land screwed. because of these two revelations, i have replaced scarscale ritual with two significantly better cards: magus of the scroll and swamp. also, my results may be skewed because i only played against control, but the land destruction proved quite effective overall.
